| Abstract: | The layered compound Li2O•2Al2O3•nH2O was synthesized by using hydrothermal route in the temperature range of 100-250℃, its structure was analyzed by X-ray diffraction patterns. The experiments showed that the formation of Li2O•2Al2O3•nH2O was influenced by synthesis conditions, including the kind and the ratio of reaction components, temperature et al. The results of thermal analyses suggested the dehydration of its layer water and structural water at 160℃ and 230℃ respectively, and the water content was determined accordingly. The ionic conductivities of Li2O﹒2Al2O3﹒nH2O at various temperatures demonstrates its satisfactory electrical property. |
